Commercial vs. Residential Roofing: A Different Kind of Challenge

While both commercial and residential roofs protect a building from the elements, they are fundamentally different in their design, materials, and maintenance needs.

These commercial roofing systems are designed for superior resistance to punctures and UV radiation, which is essential for commercial buildings that house extensive rooftop equipment and must endure severe weather.

Installation and Maintenance: A Specialized Roofing Approach

Installation for any commercial roof types, but especially the low-slope designs common on large structures, requires specialized techniques to prevent water pooling and ensure proper drainage. Due to their complex design and rooftop equipment, they also need a more rigorous and proactive commercial roofing maintenance schedule than residential roofs. Regular inspections and specialized care are key to catching minor issues before they become costly leaks, especially after severe weather events.
